Option 1: 36.47
Option 2: 37.34
Option 3: 35.67
Option 4: 38.77
Correct Answer: 36.47
Solution :
From the given graph:
Price of diesel over the years 2006-2012 = 33.65, 32.85, 34.04, 32.76, 38.51, 40.01, and 43.47
Total years = 7
Average of diesel prices over the years 2006–2012 $= \frac{\text{Sum of price}}{\text{Total years}}$
$= \frac{33.65+32.85+34.04+32.76+38.51+40.01+43.47}{7}$
$= \frac{255.29}{7}$
= 36.47
Hence, the correct answer is 36.47.
